- Construction (seven elements in five groups), f/4.5–32, 2.5 m closest focus, 67 mm filter, 107 mm length and 870 g are from Tamron USA's product page for the lens as archived in June 2004. Japanese Wikipedia, citing プロフェッショナル中判カメラ p.113 and クラシックカメラ専科No.57, and camera-wiki's SQ table give the same construction, focus distance and filter; camera-wiki also gives the same length and weight.
- Years: 1996 is the earliest dated document found (Tamron USA's SQ price list of April 1996), not a launch date; no source consulted says when the PS 200 replaced the S 200. The 2003 end is the end of SQ-Ai production (September 2003, camera-wiki); Tamron USA still listed the lens in 2004.
- Prices: $2,233 is Tamron USA's April 1996 list price and $2,531 the 2004 list price, both US distributor figures; no Japanese yen list price was found.
- The blade count is not given by any source consulted.
- The earlier Zenzanon-S 200mm f/4.5 (five elements in five groups, 97 mm, 740 g) is a different optical formula and has its own page.
How to tell them apart
- ZENZANON-PS on the name ring; the S version of the same focal length is 97 mm long and 740 g against 107 mm and 870 g here (camera-wiki)
- 67 mm filter thread, shared with every SQ lens from 50 to 250 mm except the PS 50 (77 mm); the PS 500 takes 122 mm (camera-wiki)
- SQ bayonet with the lens-mounted leaf shutter; the 200mm f/4.5 lenses marked PE or E are for the 6×4.5 ETR, and the Zenzanon-PG 200mm f/4.5 is the 6×7 GS-1 lens
Zenzanon-PS 200mm f/4.5:
- Name ring reads ZENZANON-PS 1:4.5 f=200mm; the PS suffix is the only generation this page covers
- Seven elements in five groups, f/4.5–32, 2.5 m closest focus, 67 mm filter, 107 mm long, 870 g (Tamron USA's 2004 product page; camera-wiki and Japanese Wikipedia agree on the construction and focus distance)
- Seiko #0 electronic leaf shutter in the lens and the four-claw SQ bayonet; fits every SQ body from the 1980 SQ to the SQ-B
- Zenzanon-PS 200mm f/4.5: The second-generation 200 of the SQ system, a seven-element recomputation of the five-element Zenzanon-S 200mm f/4.5. The earliest dated document in hand is Tamron USA's April 1996 price list, where it is the only 200mm; its launch year is not recorded in any source consulted. It was still on Tamron USA's 2004 list, after SQ-Ai production ended in September 2003.

History
The Zenzanon-PS 200mm f/4.5 is the second and last 200 of the Bronica SQ 6×6 system, a seven-element, five-group recomputation of the five-element Zenzanon-S 200 that the system launched with in 1980. Tamron USA’s product page gives f/4.5 to f/32, a closest focus of 2.5 m, a 67 mm filter, a length of 107 mm and a weight of 870 g; Japanese Wikipedia and camera-wiki agree on the construction and the distance. The leaf shutter is in the lens, a Seiko #0 timed electronically by the body, with 1/500 available mechanically when the battery is dead, and the four-claw SQ bayonet mounts on every SQ body from the original SQ to the SQ-B.
When the PS replaced the S is not recorded in any source consulted. Japanese Wikipedia takes the PS construction from the Professional Medium Format Camera book and the Bronica issue of Classic Camera Senka and the S construction from the 1982 yearbook, without a changeover date; the earliest dated document in hand is Tamron USA’s April 1996 price list, where the 200mm is the PS at $2,233, and the lens was still on Tamron’s list in 2004 at $2,531, after SQ-Ai production had ended in September 2003. The years on this page are therefore documented-by dates, not a launch.
No published review of the PS 200 was found in English or Japanese; the search returns dealer copy and listings only. The lens is described there as a portrait and studio telephoto, which is what a 200 on 6×6 is: roughly the view of a 110 on 35mm film, with f/4.5 at 2.5 m giving a head-and-shoulders frame. A buyer should check that the lens shutter fires at every speed on a body, that the aperture ring and blades work through f/32, and that the groups are clear of haze. The S and PS share focal length, aperture, filter and closest focus, so the name ring is the only reliable tell in a listing photograph; the PS is 10 mm longer and 130 g heavier.
Open points: the launch year, the blade count, a Japanese list price, and any first-hand account of its rendering.
This history is AI-written, from the sources listed at the foot of the page. Where the record is silent it says so rather than filling the gap — but no human wrote these sentences.
